TEST - Classic Tube Tester - Hickok 539C Here's a working Hickok 539C Tube Tester. The standard for testing vacuum tubes back in the day. Original owner was NASA Labs. I diligently went through tester and replaced all out of range resistors and calibrated it about 10 years ago and used it to test 1000s of tubes. * The cosmetics are a bit worn - cover is rough. Tester is working and accurate. Needs a knob for VR adj (seldom used) and dual banana plug jack for plate current is cracked. * Also can include a variac that helps with accuracy and drift especially with power tubes. * It's been a great workhorse for me. * $750 plus UPS Ground shipping (quite heavy) from GA (31088) or possibly can meet up with you along 95 when I make next trip to Northern VA / MD / DC (22031) passing through SC and NC. * More pics avail * Paypal or Zelle will work. 73, John K3US/4 Middle GA Listing #1756071 by K3US Last Edited on 01/17/26 Submitted on 01/17/26 Submitted from 162-239-234-159.lightspeed.tukrga.sbcglobal.net Click to Contact Back to Previous Page
